From the never-thought-I’d-do-this department: In August 2021, I stood atop California’s Mount Whitney at 14,505 feet, the highest point in the continental USA, as part of my 243-mile trek on the John Muir Trail. Seven months later, I stood at the USA’s lowest point, 282 feet below sea level, at Death Valley, as part of my cross-country RV adventure. Just 106 miles separates the two places.
